  1. with gmail default settings under accounts (apps with account access/allow less secure apps – OFF), how can i send mail to gmail.

    • @Jai,

      You don’t need to On/Off default settings of Gmail, just have correct DNS MX record in place for your domain to send mails out using mutt command.

  2. 1) Hi team i read in the notes above that in command line or code where i am calling mutt for sending mail, if i need to change my sender id i need to update the .muttrc file at ~/.muttrc, can you confirm if my understanding is correct and it is the only option available ? If that is the only option can you share the tag name which needs to be used to update the sender id.

    2) Do we have any option which we can use to have a different replyto option ? i read option ‘t‘ is available to change the recipient address, can you help to confirm on this.

    • @Mikhil,

      Yes ~/.muttrc only file, where you can specify user related configuration and about replyto option, I never used it, but you should give a try and see..

  3. Hi,

    I am new to Linux, trying to learn how to Linux command line. I just got to play with “mutt” mail utility but somehow when I wanted to delete an email (after “mutt” mail displayed a list of mails) I could not delete it (Google says: “tag” before removing) I can not “tag” the one that I wanted to remove. Can anyone help ?

    Thank you very much

  4. Hi,

    When you enter the above command in the terminal, it opens up with an interface and confirms the recipient address and subject of the mail and opens up the interface, here you can make changes to recipient mail address.

    But i don’t want this interface to come up. Actually i am try to write a script to send email for every 2 hours automatically but mutt is not usable for my requirement as manual inputs are required for each time.

    Please help to share the option .


  5. First of all, this site has been very helpful to me. Thank you.

    I have a script file that reads:

    set realname="Client Name”
    set from = "[email protected]"
    set use_from=yes
    set envelope_from ="yes"

    At the receiving end, the email address ([email protected]) works great whether you click on it in the header or if you use REPLY.
    Where it fails is if you send it to an invalid address. It does not let you know it failed.

    Is there another something I should set? A SENDER setting?

    If I send it to [email protected] I get no notification that the email could not be delivered. I do if I send it from my personal address, so I know that there isn’t really a [email protected].

    My client needs to know if their invoices and statements are not being received.

    Any help would be greatly appreciated.

  6. Is it possible to send mail with attachment in command line?

    Now when I, for example, put in “mutt -s “Test Email[email protected] after that see mutt interface where I have to confirm many things. I don’t want it.

    I need an application which send me an email with an attachment from a command line without any confirmation. Only one command, enter and nothing more

  7. I want to send the report of more than 400k records in CSV as an attachment but ‘mutt’ is not working, could you please help me in this.
